The Henry's Law constant for acetic acid has been experimentally determined to be 1.43X10-7 atm-cu m/mole at 25 deg C(1). This Henry's Law constant indicates that acetic acid is expected to be essentially nonvolatile from water surfaces(2). Acetic acid's Henry's Law constant indicates that volatilization from moist soil surfaces is not expected to be an important fate process(SRC). Acetic acid is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 15.7 mm Hg at 25 deg C(3).

A log Koc of 0.00 (Koc = 1), which was derived from experimental measurements, has been reported for acetic acid(1,2). According to a classification scheme(3), this Koc value suggests that acetic acid is expected to have very high mobility in soil. No detectable sorption was measured for acetic acid using the OECD Guideline 106 method employing an acidic forest soil, pH 2.8, an agricultural soil, pH 6.7, and a lake sediment, pH 7.1(4). Adsorption of acetic acid to 3 nearshore marine sediments collected from three different locations resulted in Kd values of 0.65 (Koc = 228), 0.085 (Koc = 6.5) and 0.046 (Koc = 27) using clastic mud (3.5% organic carbon, pH 7.0), muddy sand (1.3% organic carbon, pH 7.7), and carbonate sand (0.17% organic carbon, pH 8.1), respectively(5). The pKa of acetic acid is 4.76(6), indicating that this compound will exist partially in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(7).

Literature: #In 24 hr aqueous adsorption studies using montmorillonite and kaolinite clay adsorbents, 2.4-30.4% of added acetic acid was observed to be in the adsorbed phase(1). In adsorption studies using the adsorbent hydroxyapatite (a mineral which occurs in the environment as a result of the diagenesis of skeletal apatite), only 5% of added acetic acid (in aqueous solution, pH 8.0) became adsorbed to the hydroxyapatite(2). Acetic acid has been noted to leach from biological disposal areas(3).

The Henry's Law constant for n-butanoic acid is measured as 5.35X10-7 atm-cu m/mole(1). This Henry's Law constant indicates that n-butanoic acid is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 64 days(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 471 days(SRC). A pKa of 4.82(3) indicates n-butanoic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(4). n-Butanoic acid's Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). n-Butanoic acid is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.65 mm Hg(5).

The Koc of n-butanoic acid is estimated as 64(SRC), using a log Kow of 0.79(1) and a regression-derived equation(2). Experimental Koc values for n-butanoic acid on a clastic mud (3.5% organic carbon), a lateritic muddy sand (1.3% organic carbon), and a fine carbonate sand (0.17% organic carbon) were 19.1, 27.6, and 14.7, respectively(3). According to a classification scheme(4), these estimated and experimental Koc values suggest that n-butanoic acid is expected to have very high to high mobility in soil. The percent of n-butanoic acid sorbed to a kalonite or montmorillonite clay at 22 deg C was 14.0% and 19.9% after 48 hours, respectively, which increased to 31.4% and 24.2%, respectively, after 144 hours(5). In a field study in which 100 ppm n-butanoic acid was injected underground, the retardation, relative to the linear ground-water velocity, was calculated to be 3%(6). N-butanoic acid is listed as a compound displaying an L-type adsorption isotherm, indicating that specific binding sites may be involved(7). Experimental studies in indicate that adsorption of n-butanoic acid to moist soil is dominated by attractive forces between the compound and soil and not by hydrophobic interactions(8). The pKa of n-butanoic acid is 4.82(9), indicating that this compound will primarily exist in the anion in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(10).

The Henry's Law constant for methyl mercaptan is estimated as 0.0031 atm-cu m/mole(SRC) derived from its vapor pressure, 1,510 mm Hg(1), and water solubility, 15,400 mg/L(2). This Henry's Law constant indicates that methyl mercaptan is expected to volatilize rapidly from water surfaces(3). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(3) is estimated as 0.8 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(3) is estimated as 2.8 days(SRC). Methyl mercaptan's Henry's Law constant indicates that volatilization from moist soil surfaces is expected to occur(SRC). Methyl mercaptan is expected to volatilize rapidly from dry soil surfaces based upon its vapor pressure and because it is a gas a temperatures above 6 deg C(SRC). However, gaseous methyl mercaptan gas has been found to strongly adsorb to moist and dry soil surfaces suggesting that adsorption might be an environmental sink for methyl mercaptan(4). Therefore, the importance of volatilization from soil surfaces may be attenuated by adsorption(SRC).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of methyl mercaptan can be estimated to be 13(SRC). According to a classification scheme(2), this estimated Koc value suggests that methyl mercaptan is expected to have very high mobility in soil. Gaseous methyl mercaptan has been observed to partition to soils(3). For example, when gaseous methyl mercaptan was passed over six air-dried and moist (50% field capacity) soils, 2.4-32.1 mg/g and 2.2-21.4 mg/g of methyl mercaptan rapidly adsorbed to the dry and moist soils, respectively(3). Neither the capacity or rate of sorption was correlated to soil pH, organic matter content, or clay content; sterile controls ruled out the involvement of microorganisms(3); it was suggested that adsorption to soil surfaces might be an environmental sink for gaseous methyl mercaptan(3).

A pKa of 4.87(1) indicates propionic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(2). Propionic acid is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 3.35 mm Hg(3).

The Koc of propionic acid is estimated as 36(SRC), using a log Kow of 0.33(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that propionic acid is expected to have very high mobility in soil. The pKa of propionic acid is 4.87(4), indicating that this compound will primarily exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

Isobutyric acid [UN2529] [Flammable liquid]

533-90-4 (calcium salt)

19455-20-0 (potassium salt)

22228-82-6 (ammonium salt)

Isobutyric acid, puriss. p.a., >=99.5%

InChI=1/C4H8O2/c1-3(2)4(5)6/h3H,1-2H3,(H,5,6

A pKa of 4.84(1) indicates isobutyric acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces and moist soil is not expected to be an important fate process(2). Isobutyric acid is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 1.81 mm Hg(3).

The Koc of isobutyric acid is estimated as 77(SRC), using a log Kow of 0.94(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isobutyric acid is expected to have high mobility in soil. The pKa of isobutyric acid is 4.84(4), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
